Compared with prior art, the invention discloses cast-in-place concrete pile bubble eliminator, this device includes and the bubble eliminator of building pipe and being connected, can stir concrete when building pipe and stretching into and build in stake holes, bubble in the concrete that effective removal is built, bubble eliminator of the present invention comprises upper and lower two-layer stirring structure, and bilevel mixing direction is adjustable, through double-deck stirring, improve the ability that this device removes the bubble in the concrete of building further.What bubble eliminator of the present invention was applied to rigidity builds tubular structure, build pipe lower side and offer discharge opening, discharge opening position is higher than bubble eliminator, top is fixed on earth's surface or concreting car, existing rigidity builds pipe two kinds, one automatic rotation when building, for automatic rotation builds pattern, another maintains static exactly, for fixing non rotating builds pattern, under these two kinds of patterns, the working method of bubble eliminator is required different: if automatic rotation builds pattern, build pipe to rotate with bubble eliminator, do not need bubble eliminator self-powered, if the bubble eliminator that positive and negative twocouese stirs, then very be not applicable to automatic rotation and build pattern, because one of them mixing plant meeting and to build the direction of rotation of pipe contrary, good effect cannot be played, if gate spool is fixed and is non-rotaryly built pattern, build pipe motionless, need bubble eliminator autorotation, preferably twocouese ground stirs simultaneously.These two kinds differences of building pattern make the bubble eliminator structure of each self application different, cast-in-place concrete pile bubble eliminator of the present invention can effectively address this problem, build pipe to be directly fixedly connected with the motor fixing frame be located in the drive mechanism of middle level, motor fixing frame is fixed by left connecting rod and right connecting rod and transmission bracket, the power transmission shaft of motor directly stretches in lower rotor plate fixing (for convenience of statement, the rotor plate of upper rotor plate and upper strata mixing plant, the rotor plate of lower rotor plate and lower floor's mixing plant, the teeter column of upper teeter column and upper strata mixing plant, the teeter column of lower teeter column and lower floor's mixing plant), design motor fixing frame can make each connecting rod directly be connected on motor, the effect of protection motor can be played.When build pipe be in automatic rotation build pattern time, motor does not operate, now motor, motor fixing frame, transmission bracket, lower rotor plate is integrated fixing, along with the rotation synchronous rotary of building pipe, and upper rotor plate is owing to being fixedly connected with top helical gear, top helical gear through left side helical gear can promote also can with build pipe synchronous rotary, such as, when building pipe and rotating clockwise, transmission bracket, lower rotor plate, left side helical gear, right side helical gear, the end entirety of helical gear composition also rotates clockwise, left side helical gear and right side helical gear force the top helical gear be engaged with it also to rotate clockwise, and then drive upper rotor plate to rotate clockwise, upper teeter column and lower teeter column realize equidirectional rotation.When build pipe be in fixing non rotating build pattern time, motor operates, motor power can be electric wire connection external power source also can be the battery carried, motor transmission shaft drives lower rotor plate to rotate, the equidirectional rotation of end helical gear fixing on lower rotor plate, drive left side helical gear and right side helical gear, left side helical gear and right side helical gear drive top helical gear again, after this series of drive coordinates, top helical gear counter-rotation, make rotor plate also counter-rotation, realize the technique effect that upper and lower teeter column mixing direction is contrary.Such as, when motor operates, motor transmission shaft drives lower rotor plate to rotate clockwise, lower teeter column also can rotate clockwise, after the helical gear transmission in end helical gear, left side helical gear and top coordinates, top helical gear rotates counterclockwise, and in drive, rotor plate rotates counterclockwise, and the upper teeter column on upper rotor plate also rotates counterclockwise.Mutually snap between plate side channel on cannelure bottom left and right sides supporting plate and lower rotor plate, make left and right sides supporting plate can carry out on vertical direction to lower rotor plate spacing, share the axial force from lower rotor plate that a part of motor transmission shaft is subject to, the horizontal component that two plates connect is provided with sealing floating ring, form three seals, effective prevention mortar and water penetrate the central cavity of transmission bracket, ensure the normal operation of motor.Bubble eliminator of the present invention is also provided with the function that diameter is stirred in adjustment, the extension elongation of teeter column and lower teeter column can be regulated, bubble eliminator of the present invention is made to go for the concrete pile of different-diameter, the means adopted are in regulating tank, be in axial direction placed with several dish tooth spring, teeter column is provided with the screens cannelure suitable with tooth, is realized the adjustment of the extension elongation to upper teeter column and lower teeter column by screens cannelure and the tooth phase screens of diverse location.Such as, when stake holes is larger, allow screens cannelure and outer dish tooth spring screens, and then bubble eliminator is contained on teeter column, when stake holes is less, allow screens cannelure with by inner dish tooth spring screens, and then bubble eliminator to be contained on teeter column.When screens cannelure is with during by inner dish tooth spring screens, outer dish tooth spring teeter column bends by force.The interior extreme direction of the teeth directional regulating tank of dish tooth spring bends, teeter column ratio is made to be easier to dish tooth spring to bend, and the dish tooth spring of this shape can prop up screens cannelure and makes teeter column be difficult to outer under the influence of centrifugal force moving, the present invention has a dish tooth spring to be arranged between regulating tank outer end and adjusting bolt, when adjusting bolt is positioned at the inner and teeter column level of sliding position groove, this dish tooth spring just in time can snap in screens cannelure.The benefit of such setting directly can move teeter column to outermost state when bubble eliminator is set in maximum stirring diameter, then directly snaps in dish tooth spring, eliminates the trouble of alignment dish tooth spring and screens cannelure, use convenient.By coordinating of dish tooth spring and teeter column, realize the reducing of bubble eliminator.Along with the carrying out of building, build pipe slowly to promote along with the lifting in the face of building, be fixed on the bubble eliminator of building bottom pipe also slowly to promote along with building pipe, keep discharge opening to be positioned at concrete surface top by arranging the hoisting velocity of building pipe, and bubble eliminator is positioned at concrete surface bottom.
The present invention have can tackle simultaneously two kinds build pattern, double-deck can stir the bubble effectively removed in cast-in-place concrete pile, can along with the Process Synchronization lifting of building, the advantage of stake holes that can adapt to different-diameter.
